About me
I'm a QA Engineer helping startups and developers ship bug-free software.
With 50+ tested projects, I specialize in:
• Web application testing
• Mobile apps (iOS & Android)
• Video games
• E-commerce & checkout flows
• AI-generated apps (Cursor, Bolt, Lovable)
I test on real devices: PC, Mac, iPhone, iPad, Android phones and tablets — even Apple Vision Pro.
What you get: detailed bug reports with screenshots, steps to reproduce, and severity levels. Ready to send to your developers.
Fast communication. Clear reports. Bugs found before your users do.
Let's talk about your project.
